Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584212, here are decompositions:
- 19 + 31584193 = 31584212
- 73 + 31584139 = 31584212
- 193 + 31584019 = 31584212
- 223 + 31583989 = 31584212
- 229 + 31583983 = 31584212
- 241 + 31583971 = 31584212
- 271 + 31583941 = 31584212
- 349 + 31583863 = 31584212
Showing the first eight; more decompositions exist.
